Rumorpile: GM's Current CEO Could Step Down Next Year

General Motors' current CEO, Dan Akerson, could be stepping down as early as next year, according to a report from Reuters.

Sources tells Reuters that Akerson hasn't formally notified GM's board of directors of any plan to step down, but could come to fruition some next year.

"I assume at some point he (Akerson) will decide he has done what he has wanted to do and will step down, but no one has a date for that," said a source.

Now the board has a succession plan in place if Akerson makes a decision to step down. But according to sources, the board hasn't set a timeframe to begin a search for a new CEO. This will most likely change when Akerson makes a decision.

Who are the possible contenders for GM CEO? Well the running favorite is GM's North American President, Mark Reuss. Also in the running are Mary Barra, GM's product development lead; Steve Girsky, GM's vice chairman; and Dan Ammann, GM's CFO.
